DUI Accidents The number one cause of most motor vehicle accidents is negligence. Negligence is legally defined as the failure to act with the same amount of caution a normal person would exercise in the same situation. Common negligent driving behaviors include: disobeying traffic signs, disobeying traffic laws, talking to other passengers, talking on cell phones, and driving under the influence. When people drive under the influence of drugs and/or alcohol, they not only endanger them selves, but also the lives of others. People who drive under the influence cause numerous fatal accidents each year. For this reason, people who are facing DUI/DWI Accident charges may be susceptible to serious legal consequences if they are convicted.
